Title: Improvements in or relating to circuit arrangements embodying electronic storage tubes
Inventor: WEBLEY REGINALD SIDNEY
IPC: H01J31/64
Filed: 1951-04-11
Abstract: 714,924. Electron beam apparatus. ELECTRIC & MUSICAL INDUSTRIES, Ltd. April 4, 1952 [April 11, 1951], No. 8354/51. Class 39(1) An electronic storage tube comprises an electron permeable storage electrode including a conducting member having an insulating charge storage surface, means for applying charges to the storage electrode, a cathode for generating an electron beam which scans the storage electrode at low velocity so as to cause the beam to be modulated in intensity by charges stored on the storage electrode, means for collecting the modulated electrons passing through the storage electrode, and means for maintaining the conducting members of the storage electrode at a positive potential with respect to the cathode. In the arrangement shown in Fig. 1 the storage electrode 6 is charged by electrons from a gun 2 which is modulated in accordance with the signals to be stored and may charge the electrode 6 positively by secondary emission. A slow beam from the gun 8 is used for reading, the beam passing through the electrode 6, being modulated by the charges on it, and finally reaching a collecting electrode 5.. To discharge the electrode 6, the gun 8 is pulsed to a potential higher than that of the mesh electrode 7 so that electrons from the gun 8 pass through the electrode 6 and are then reflected back on to it to remove the charges. The electrode 6 may alternatively be charged negatively from the gun 2 or may be charged by bombardment induced conductivity. In constructing the tube, three metal rings, 19, 20 and 21, Fig. 2, are secured to insulating rods 22 sealed to the envelope at 23. Each ring is provided with a pair of lugs 24 each provided with a short length of wire projecting from it. After the narrow neck portion to the right of Fig. 2 has been sealed on, the electrodes 7, 6 and 11 of Fig. 1 which are mounted in metal rings are introduced through the neck portion and seated against the lugs 24, the wires 25 being bent over to secure them in position. In the modification shown in Fig. 3, electrons from a photo-cathode 30 are used to charge the electrode 6, the reading being performed as in Fig. 1 by electrons from the gun 8 passing through electrode 6 to the signal electrode 33. The photo-cathode may be used to charge the electrode 6 either positively or negatively and may be pulsed to an appropriate potential and flooded with light when it is desired to remove the charges. This tube may be used as a television pick-up tube; after a line has been scanned by the beam from the gun 8 the fly-back is used to discharge the line that has just been scanned by pulsing the gun 8 to such a potential that electrons pass through the electrode 6 and are reflected back on to it. Specification 599,747 is referred to.

Abstract: 927,529. Electrolytic processes for obtaining electrolytic iron. TOHO AEN KABUSHIKI KAISHA. March 8, 1962 [July 15, 1961], No. 8930/62. Class 41. Electrolytic iron is produced by electrolysis with an anode of pig iron, or high carbon steel containing at least 1% by wt. carbon, and at least 0.4% by wt. of copper and an aqueous solution of Mohr's salt bath (FeSO 4 .(NH 4 ) 2 SO 4 . 6H 2 O) as electrolyte to deposit refined iron on the cathode. The anode preferably contains 1.1 to 2.5% by wt. copper and 1.0-2.4% by wt. carbon. The copper-containing pig-iron anode derives from reduction melting of zinc slags after recovery of zinc therefrom. The copper forming as a network on the surface of the dissolving anode serves to trap the anode impurities and insoluble constituents such as carbon, silicon, silver and gold thereby preventing the deposition of anode slime and colloidal contamination of the electrolyte. The copper advantageously forms local electric cells - with the iron base which enhance the dissolution of the anode. The anode slime is recovered and metal values extracted therefrom.
